Abstract: PURPOSE:To stabilize a reproducing signal by counting a two-phase signal with a phase difference of 90 deg. from a magneto-resistance effect element, forming a control signal by comparing the count value with a reference value, and also, controlling the driving voltage of a motor on a supply reel side by the control signal. CONSTITUTION:A magnetic drum 2 on which multipolar magnetization is applied is integrated with a tension arm 1, and the magneto-resistance effect element 3 is provided oppositely to the magnetized part, and the two-phase signal with the phase difference of 90 deg. outputted from the MR element 3 is counted by an up/down counter 4, meanwhile, the envelope of the reproducing signal from a tape 10 is detected, and the intensity of tape tension is decided by the envelope signal. And the output data of the up/down counter 4 is processed based on the above result, thereby, the driving voltage of the motor on the supply reel side is controlled. In such a way, it is possible to stabilize the reproducing signal in a state from the start of the winding to the end of the winding of the tape.

Title: Production of surface acoustic wave filter electrode
Inventor: DEGUCHI YOSHIYUKI
IPC: H03H3/08
Filed: 1996-10-25
Abstract: PROBLEM TO BE SOLVED: To produce a surface acoustic wave filter electrode which is never eroded in an etching process where a local voltaic cell on is suppressed by carrying on the dry etching until the wafer surface is etched and completing the etching process by the wet etching. SOLUTION: An electrode material thin film (b) is formed on a wafer (c) at an early stage, and the resist (a) is prepared at a proper position on the film (b). The dry etching is carried on until the surface of the wafer (c) is etched. Then the wet etching is carried on until the surface of the wafer (c) is etched. Finally, the resist (a) is eliminated in a resist elimination process. Thus, the erosion of an electrode caused by the Cl ion of the gas component used for etching can be prevented. In such a way, the dry etching is carried on until the wafer surface is etched and then the wet etching is carried after the wafer is washed in the water. As a result, the remaining erosion component is washed out and the promotion of the voltaic cell function due to Li of the wafer component is suppressed.

IPC: G06F17/28
Filed: 1986-11-28
Abstract: PURPOSE:To translate punctuation signal by using the information on the position where the colon or semicolon mark emerge in an input English sentence and discriminating the dictionary parts of speech (verb, noun, pronoun, conjunction) that is added to the mark. CONSTITUTION:A translation module 5 contains a grammar rule. When an input sentence is inputted via a keyboard 4, a CPU 1 adds a period to the end of the sentence together with the dictionary consulting jobs and stores the sentence into a buffer if this input sentence has a semicolon (;) at its end. It is supposed that the semicolon is previously registered in a dictionary for the module 5 in the form of period, pronoun and conjunction. If it is known that a period is put after a semicolon in the next judgement, the registered conjunction of semicolon is deleted out of a dictionary consulting result buffer. Then the sentence is analyzed into a prescribed tree structure after analyses of morpheme and syntax structure. The semicolon is interpreted as pronoun. The pronoun is translated based on the definition of the dictionary and displayed.

Filed: 1997-10-01
Abstract: PROBLEM TO BE SOLVED: To enable stable long-time power generation, by inducing electric fields in a conductor placed close to a rotor containing a superconductor of the second kind without contact, and taking out its output. SOLUTION: A generator is provided with superconducting magnets 101, a rotor 103 containing superconductor of the second kind which is rotated on a rotary shaft 104, and a stationary conductive member 102 placed nearby opposite to the face of the rotor. The rotor 103 is rotated on the rotary shaft 104 in magnetic fields produced by the superconducting magnets 101, thereby inducing electric fields in the conductive member 102. Then power is taken out of output terminals 105 connected with the ends of the conductive member 102. Since the superconductor with magnetic flux pinned is rotated, the magnetic flux is moved in the stationary conductive member 102 according to the rotational speed of the rotor 103, and electromagnetic force is exerted on charge carriers in the radial direction due to Lorentz force.  As a result, electric fields are produced, and direct-current power generation can be performed. Thus the enhancement of the reliability and stability of power generating operation and lengthening of life can be achieved without use of any brush.

Filed: 1992-10-01
Abstract: PURPOSE:To improve the driving precision by installing a means for compensating the relative control error between a first control loop and a second control loop, in a driving control equipment provided with the first and second control loops and a means for generalizing and controlling the whole. CONSTITUTION:After the driving amount determined by the second control loop L2 is driven by the first control loop L1, the driving amount is again measured by the second control loop L2. An operator 1 calculates the relative control error between the first control loop L1 and the second control loop L2. A relative control error compensator 2 samples the control error at each driving command, and forms time series data. By operating an arbitrary number of data existing in an arbitrary time section, secondary control data are formed. The secondary control data are reflected to control driving, thereby dissolving the relative error between the two control loops L1, L2. Hence driving precision can be improved.
